Hey! I'm a val.town fanboy and I immediately thought about a workaround while reading the blog post:
What if I dumped every publics vals in Github, in order to be able to user their (awesome) search ?
So here is my own "Val Town Search": https://val-town-search.pomdtr.me
And here is the repo containing all vals, updated hourly thanks to a github action: https://github.com/pomdtr/val-town-mirror
